Kelly Osbourne is in trouble with tax authorities – she allegedly owes the State of California more than $30,000. Court documents filed in Los Angeles County and obtained by TMZ.com allege Ozzy Osbourne’s daughter failed to pay $34,763.30 in back taxes in 2009, the year the rock offspring waltzed her way to third place on reality show Dancing with the Stars.

And her financial troubles don’t end there – Kelly discovered she had become a victim of credit card fraud on Saturday.

In a post on her Twitter.com blog, she writes, “Someone stole my credit card and rented a car with it. What a dumb a** you need to show I.d to rent a car!!!”
